ROSCO toolbox documentation¶

NREL’s Reference OpenSource Controller (ROSCO) toolbox for wind turbine applications is a toolbox designed to ease controller implementation for the wind turbine researcher. The purpose of these documents is to provide information for the use of the ROSCO related toolchain.
Figure Fig. 1 shows the general workflow for the ROSCO toolchain.

For the standard use case in OpenFAST, ROSCO will need to be compiled. This is made possible via the instructions found in Installing the ROSCO tools. Once the controller is compiled, the turbine model needs to point to the compiled binary. In OpenFAST, this is ensured by changing the
DLL_FileName parameter in the ServoDyn input file.
Additionally, an additional input file is needed for the ROSCO controller. Though the controller only needs to be compiled once, each individual turbine/controller tuning requires an input file. This input file is generically dubbed “DISCON.IN’’. In OpenFAST, the
DLL_InFile parameter should be set to point to the desired input file. The ROSCO toolbox is used to automatically generate the input file. These instructions are provided in the instructions for Standard ROSCO Workflow.
